The-present invention relatesto-a bindihgi devicerwhich can be arranged: in movablefiles of allikinds andfwhichis. characterised, among other advantages, .b'yv the fact thatiit can be adapted tora 3numbe-r1of documents' ofxvery. varied-shapes, since it? canensure the maintenance of'arsingle document of any, dimension as well as that of a hundred or even'more, whilst'having a thickness as reduced as possible, 'and 'that its very rapid manipulation,effected witli one-"hand only, allows tli'e'iother 1131111470 -be--lettfree fordntroducingor removing documents, without the latter being deteriorated in any way whatever.

The invention is clearly illustrated in the accompanying drawing, in which:

Figure l is a perspective view showing the binding device applied to a file,

Figure 2 is a perspective view on an enlarged scale of the binding device in open position,

Figure 3 is a perspective view of the binding device on an enlarged scale in the act of being closed, and

Figure 4 is an enlarged perspective view of the binding device in a closed position.

Figs. 5, 6 and 7 are diagrams to allow the operation of the device to be understood when it is engaged with the documents to be kept in the file.

The movable file I is provided, as near as possible to its hinge 2, with the binder 3 and the latter allows the documents 4, 5, I5 of various dimensions to be sorted as will be clearly seen in Fig. 1.

The binder proper essentially comprises a fiat base 1 serving to secure it on the file, for instance by means of two or three eyelets 8, and a partly bowed member 9, made of steel, having the shape of an H and pivotally mounted on said base.

Said base is turned upwardly according to a right angle at one of its edges to form an upstanding flange I0, bent at II and I2 at both its ends. The end II is folded to form a fork I3 in which is riveted the pin I4 on which can pivot, in a vertical plane, the main portion of the longer of the resilient bars I5 of the H-shaped member 9 according to the manipulations imparted to the latter by means of the handle portion It, pivoted to the outer end of the bar I 6 for horizontal swinging movement.

The other resilient bar I! of member 9 and which is intended to firmly grip the documents is shorter than bar I5 and is bowed upwardly longitudinally so that when member 9 is lifted vertica-lly on its pivot I4 (Fig. 2) the lower end I! of said bar remains spaced away from the base to a distance at least equal -'to the thickness" of the documents whicli'are 'to be placedin the file; The ends'or-wingsfli and I W01 bar I l are preferably 'bent 'inwardly'so'as to form wideclamping surfaces.

slightlyupset so as toform-a projection I9'*which" accentuates the-grippingof the="document-or doc uments ir i theclosed jaw formed-between" saidflange I9 and the bar H. For the same purpose, said base can be provided with projections 20 obtained by upsetting, opposite the ends II and I! of bar H (see Fig. 4).

The handle I6 can be cut out in the extension of bar I5 of the curved member 9, but it is preferable to pivotally mount it on the latter at 2I and to extend it by a small fork 22 freely engaged on a projection 23, obtained by upsetting, on the end of bar I5.

The manipulation of the device is verysimple: the document or documents to be filed having been placed with their inner edges against the flange ID of base I, it sufiices to lower the handle l6 and to engage it under the yoke or lug I8, said movement being facilitated by the pivotal joint 2|, 22 of said handle on bar I5. The device then exerts, on the filed documents, a three-fold clamping, resilient and progressive effect, first by means of the curved bar I! (Fig. 5) which transmits it to both clamping wings I1 I1 then by the cross member connecting bars l5 and I! of the H- shaped member 9, which transfers, by fiexion and torsion, on I5, the stress exerted on I! (Fig. 6), finally by bar I5 also curved, on the base I secured to the back of the file (Fig. '7)

On the other hand, it sufiices to press on the handle IE to disengage it from the yoke or lug I8 and to laterally space it away, owing to the action of the pivotal joint 2|, for the device to be lifted and cease to exert any pressure on the documents placed in the file.

It is to be understood that the embodiment described and illustrated is only given by way of example and that the profile and detailof all the members can be varied to infinity without departing thereby from the scope of the present invention. It is thus that the pivotal joint 2! of the handle might be done away with and transferred to the yoke which might pivot on the base I, that the wings I1 and I! might be double or extend only outwardly, etc.

I claim:

1. A binding device for movable files comprising a rectangular base plate, means to secure said plate to the back of a letter rack, an upstanding fiange extending along the one larger side of said base plate and bent into a fork at one end thereof, an arched lug formed at the opposite end of said flange, an H-shaped member made up of resilient strips having its larger leg hinged at one end thereof in said fork at one end of said flange on said base plate, a latch pivoted to the other end of said larger leg as an extension of the same and projections formed at either end of the shorter leg of the H-shaped member extending at right angles thereto towards said larger leg.

2. A binding device according to claim 1 wherein the shorter leg of the H-shaped member is arcuated towards the base plate.

3. A binding device according to claim 1 wherein a rib is formed in the base plate at its longer edge opposite to the flanged edge thereof.

4. A binding according to claim 1 wherein the Width of the H-shaped member is less than that of the base plate.

5. A binding device according to claim 1 wherein the longer leg of the H-shaped member is bent up at its free end.

6. Binding device for movable files comprising a rectangular base plate, means to secure the plate longitudinally to the back of a letter rack, an H-shaped member with resilient legs of unequal lengths,'the longer of the legs having one end thereof hinged transversely to one side of said base plate for vertical swinging movement with respect thereto, a lug projecting laterally from said side of the base plate adapted to catch the free end of the longer leg of the H-shaped member and the shorter. leg of the member being bowed upwardly medially of its ends and formed at either end with wings directed towards the longer leg and adapted to yieldingly bear upon the upper surface of the sheets being held.
